Deploying a Tabby Instance in Hugging Face Spaces

· 4 min read

Hugging Face Spaces offers an easy-to-use Nvidia GPU hosting runtime, allowing anyone to host their machine learning models or AI applications.

In this blog post, we are going to show you how to deploy a Tabby instance in Hugging Face Spaces. If you have not heard of Tabby, it’s an open-source Github Copilot alternative that supports code completion. Check out more details here.

How it works

Let’s firstly take a look at what steps are needed to deploy a Tabby instance in Hugging Face. It’s super easy and you don’t need much coding knowledge. Buckle up and let’s get started.

Step 1: Create a new Hugging Face Space (link). Spaces are code repositories that host application code.

Step 2: Create a Dockerfile to capture your machine learning models' logic, and bring up a server to serve requests.

Step 3: After space is built, you will be able to send requests to the APIs.

That's it! With the hosted APIs, now you can connect Tabby's IDE extensions to the API endpoint. Next, we will deep dive into each step with screenshots!! Everything will be done in the Hugging Face UI. No local setup is needed.


Looking to quickly start a Tabby instance? You can skip the tutorials entirely and simply create space from this template.

Deep Dive

Create a new Space

After you create a Hugging Face account, you should be able to see the following page by clicking this link. The owner name will be your account name. Fill in a Space name, e.g. "tabbyml", and select Docker as Space SDK. Then click "Create Space" at the bottom.

In this walkthrough we recommend using Nvidia T4 instance to deploying a model of ~1B parameter size.

Create a new Space

Uploading Dockerfile

For advanced users, you can leverage the Git workspace. In this blog post, we will show you the UI flow instead. After you click the "Create a Space" in the last step, you will be directed to this page. Just ignore the main text and click the "Files" on the top right corner.

Docker Space

After clicking on the "Files", you will be able to see a "Add file" button, click that, then click on "Create a new file"

Empty Space

Then you will be redirected to the page below. Set the filename to “Dockerfile” and copy the content to the “Edit” input box. You can copy the code from the appendix here to bring up the SantaCoder-1B model. Once ready, click the button “Commit new file to main” on the bottom.

Edit Dockerfile

Edit Readme

You also need to add a new line the Click the "edit" button in the file.


Add this line "app_port: 8080" after "sdk: docker"


Click the button "Commit to main" to save the changes.

Verify Tabby is running

Click on the "App" button, you should be able to see the container is building:

Space Building

If the App is up successfully, you should see this page:

Tabby Swagger

Call code completion API

Now, you are able to call the completion API. The full URL is https://{YOUR-ACCOUNT-NAME} In this post, the URL is

To test if your APIs are up and running, use this online tool to send curl commands:


The complete curl command can also be located in the appendix. Ensure that you have adjusted the URL to align with your Hugging Face Spaces settings!

(If you are setting the space to private, you will need to fill in your Huggingface Access Token as bearer token in HTTP Headers, like Authorization: Bearer $HF_ACCESS_TOKEN.)


In this post, we covered the detailed steps for deploying a Tabby instance to Hugging Face Spaces. By following these steps, anyone is able to bring up their own code completion APIs easily.
